Which of the following describes an action that could be considered part of procuring cause?

Procuring cause refers to the actions taken by a real estate professional that lead to a successful transaction, specifically those that are instrumental in bringing about a sale. Hosting an open house event is an effective strategy as it provides an opportunity for prospective buyers to view a property firsthand. During these events, the agent engages with attendees, answers questions, and creates interest in the property, all of which can directly lead to a sale. This kind of proactive engagement is vital in establishing the agent's role in the transaction.

In contrast, while directly negotiating with a buyer, advertising a property, and following up with interested buyers are essential components of the real estate process, they may not individually encapsulate the entire effort involved in establishing procuring cause. Therefore, hosting an open house stands out as a specific action that not only showcases the property but also actively engages potential buyers, thereby strengthening the agent's connection to the eventual sale.
